DabDab - Flowing art at your touch # Two drops, infinite ripples. In 1886, Georges Seurat completed a masterpiece built entirely from millions of tiny colour dabs. The Impressionists called this technique pointillism: one dab births a point of light; two dabs set that light in motion. Now imagine those dabs falling onto still water instead of canvas. Each touch sends ripples of colour flowing outward — expanding, colliding, merging into patterns no one could have predicted. That's DabDab. A century-old artistic spirit, reimagined for your fingertips. # The Story Behind the Name "Dab... Dab..." A dab is the brushstroke of the Impressionists — a single touch that captures light. Repeat it — DabDab — and light begins to flow. Each tap on your screen sends colour rippling outward, swirling and merging with the ones before it. Two drops. That's all it takes. # Not a Drawing Tool. A Conversation. Touch the screen and watch flowing liquid colour react to your gestures in real-time. Move slowly for gentle ripples, swipe quickly for dramatic splashes. You set the rhythm; the fluid answers. Every moment is improvised; every creation is unrepeatable. # Perfect For: • Creating mesmerising fluid animations — record and share as videos • Exporting as Live Photos to set as your Lock Screen wallpaper • Sharing stunning visual moments on social media • Finding a moment of calm and mindfulness • Exploring colour through curated themes inspired by nature • Playing with physics to discover your own style of flow # Features ## Real-Time Fluid Simulation GPU-accelerated physics renders flowing liquid colour at 120 fps. Every touch produces a natural, responsive fluid reaction. ## Curated Colour Themes Handcrafted themes, each with a unique visual character and mood — from deep ocean glow to cherry blossom softness. More themes coming soon. ## Video Recording & Screenshots Capture your fluid creations, save to your library, and share directly via the built-in share menu. Send to social media, AirDrop, or any other app in one step. ## Live Photo Export Export your fluid creation as a Live Photo. Save it to your library as a living image, or set it directly as your Lock Screen wallpaper — your flowing art comes alive every time you wake your phone. ## Attract Mode Sit back and watch the fluid dance on its own, driven by graceful mathematical curves. Choose how long the app waits before it takes over. ## Advanced Physics Controls Fine-tune dissipation, vorticity, and ink radius. Switch between presets for quick style changes, or craft your own. # Privacy First Your creations belong to you. • 100% Local: All simulation and processing happens on your device. • No Uploads: Your recordings and screenshots never leave your phone. • No Data Collection: No accounts, no tracking.

Corner Radius
Read full descriptionHide full description
Pick the exact corner radius for a button, card, sheet, or app icon — and see it live, at real size, before you write a single line of code. Most radius decisions happen blind: you type a number, rebuild, squint, and type another. RadiusPreview turns that loop into one slider. Drag it and a real, scalable shape reshapes instantly on screen — 0 to 160 pt, uniform or corner-by-corner. Flip between Apple's continuous squircle and a true circular arc and watch the difference the way your eyes actually read it. When the shape looks right, the exact CSS, SwiftUI, or SVG is already written for you, ready to copy. WHAT YOU GET - One slider that reshapes a real UI surface in real time — no rebuild, no guessing - Copy-ready CSS, SwiftUI, and SVG code for the exact shape on screen - Independent control of all four corners for sheets, chat bubbles, and tabs - A continuous-vs-circular comparison that finally explains why one looks softer - 12 ready-made presets — card, button, pill, sheet, squircle, app icon mask and more - A saved library of your shapes, so a decided radius never gets re-litigated PERFECT FOR - iOS developers matching SwiftUI surfaces to the system look - Web and front-end developers writing border-radius by hand - Product and UI designers defining a radius scale for a design system - Anyone who has ever argued about whether 12 or 16 looks better WHY NOT JUST EYEBALL IT IN THE INSPECTOR? Because a radius of 44 pt on a 260 pt card is not the same radius on a 56 pt button, and a continuous curve at 24 does not match a circular curve at 24. Seeing both at true size, side by side, takes seconds — reworking a component after it ships takes a day. LEARN A built-in Learn section explains the nested-radius rule, how to build a radius scale, the half-height pill trick, per-corner syntax in CSS and SwiftUI, and when sharp beats soft. PRIVACY Everything runs on your device. No account, no sign-in, no ads, no tracking. It works fully offline. FULL ACCESS Premium unlocks per-corner radius control, SwiftUI and SVG code export, the side-by-side continuous vs circular comparison, and all premium presets. Available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. CSS export, uniform radius, free presets, the radius scale reference, saved shapes, and the Learn section are included without a subscription. Open the app, drag the slider until the corner looks right, and paste the code into your project.
